Chuo Shoko Co., LTD

Chuo Shoko Co., LTD, a Japan-based for-profit industrial supplier headquartered in Yokosuka, Kanagawa, operates as a prime contractor providing industrial chemicals, equipment, and maintenance materials to U.S. naval installations throughout Japan, competing in full and open (unrestricted) federal procurements with no small business set-aside designations.

The vendor's federal footprint centers on industrial chemical supply. Chuo Shoko specializes in calcium hydroxide, sodium hydroxide, and hydrochloric acid—the three chemicals that appear across the vast majority of its delivery orders and purchases—alongside maintenance equipment and specialized supplies for naval facility operations. Representative work includes a $371,025.60 single-award IDC (March 2026 to April 2028) with Naval Facilities Engineering Command for sodium hydroxide and hydrochloric acid delivery to Commander Fleet Activities Yokosuka; a $211,641.00 three-year single-award IDC (March 2026 to March 2029) for calcium hydroxide to the Solid Waste Incineration Plant at CFAY; and recurring monthly delivery orders under an expired $872,713.67 IDC with NAVFAC for sodium hydroxide, typically valued between $6,000 and $22,000 per order. The vendor also supplies miscellaneous equipment—spot coolers, chain hoists, pneumatic tools, cable assemblies, and maintenance parts—to Naval Sea Systems Command and Naval Supply Systems Command through individual purchase orders.

Customer concentration is extreme and focused entirely on Department of the Navy commands. The top five customers account for 97% of awards. Naval Facilities Engineering Command leads by volume (525 awards, $6.4 million combined potential value), followed closely by Naval Sea Systems Command (349 awards, $5.3 million) and Naval Supply Systems Command (117 awards, $6.5 million). Naval Installations Command (25 awards, $353 thousand) and Bureau of Medicine and Surgery (4 awards, $77 thousand) round out material activity. The dollar ranking differs slightly from volume: Naval Supply Systems Command anchors the highest potential value at $6.5 million despite fewer award count, driven by larger IDC ceilings.

Chuo Shoko holds five major indefinite delivery contract vehicles. The largest is IDC N6264907A0086 with 335 task orders totaling $3.9 million combined potential value. Secondary vehicles include IDC N6264997A0024 (215 task orders, $101 thousand), IDC N6264920D0002 (85 task orders, $1 million), IDC N6264923D0003 (70 task orders, $1 million), and IDC N6264920D0008 (37 task orders, $124 thousand). All are single-award, non-set-aside indefinite delivery contracts issued by various Naval commands for recurring chemical and equipment procurement.

Activity has been steady and flat. The vendor sustained 40 awards in 2022, 48 in 2023, 49 in 2024, and 42 in 2025, with 4 awards recorded through March 2026. The combined potential value across all 1,076 awards in the source footprint is $18.7 million, with $12.5 million obligated (67%). Chuo Shoko has maintained continuous federal registration in SAM.gov since December 2006 and has been a Navy vendor for nearly two decades, with the oldest recorded award dating to December 1996.

The vendor competes exclusively under unrestricted (non-set-aside) vehicles; all awards carry "No Set-Aside Used" designations. Place of performance is Japan for all work. Chuo Shoko operates as a 100% prime contractor with no recorded subcontract footprint in the source data. The source data includes no evidence of teaming relationships, joint ventures, or subsidiary arrangements. Primary NAICS codes reflect the vendor's commodity mix: Industrial Machinery and Equipment Merchant Wholesalers (344 awards), Industrial Gas Manufacturing (159 awards), and Lime Manufacturing (63 awards). Top PSC codes are Chemicals (304 awards), Hose and Fittings (43 awards), and Hand Tools (37 awards).
